Coordinate Reference System Calculations

Transform latitude and longitude coordinates into another CRS via Proj4js.

This example demonstrates how to use the Proj4js coordinate transformation library in a data event script to automatically calculate the coordinates for a defined CRS. In this case we are listening to the change-geometry event and projecting the latitude and longitude coordinates to EPSG:2193, New Zealand Transverse Mercator (NZTM). The NZTM coordinates are written to X and Y numeric fields, which are set to decimal and read-only.
